Not many moments in life change the course of history, shatter the status quo and usher in a paradigm shift. Such a moment took place in 1973 at the Chateau de Versailles when American designers Anne Klein, Stephen Burrows, Oscar de la Renta and Halston stormed the French haute couture establishment -- Yves Saint Laurent, Christian Dior, Hubert de Givenchy, Pierre Cardin and Emmanuel Ungaro. In front of an A-list audience including Andy Warhol, Princess Grace of Monaco, Christina Onassis and Josephine Baker, the Americans catapulted ready-to-wear to global stardom. Their secret weapon was fresh, innovative designs and the tour de force, a collective of stunning black models who sashayed down the runway and into the hearts of the high-profile audience.
